One 、 Application and characteristics of the product
LLJ Series leakage relay ( Hereinafter referred to as relay ) Suitable for AC voltage of 660V. to 1140V Voltage system , The frequency is 50Hz, electric current 15~4000A Whether there is neutral leakage protection in the line .
The relay can be connected with the circuit breaker with shunt release or voltage loss release 、 AC contactor 、 Magnetic starter and other components of leakage protection device , For leakage and electric shock protection , Can be equipped with buzzer 、 Various sound and light indicating devices such as signal lamps are combined to form a leakage alarm device .
LLJ The relay is divided into guide rails . The panel can be installed in two ways . Small volume 、 Easy to use , The action value is fixed or adjustable by grades , Reliable movement , Continuous power supply is stable , Easy to operate . Can adapt to users everywhere , It can be used to protect the line from ground fault , Prevent equipment accident or electrical fire caused by grounding fault current , It can also be used to relieve the electric shock of human body and provide indirect electric shock protection . It is applicable to the low-voltage distribution system with the center point of the power system directly grounded or the distribution system without neutral point grounding in the coal mine , It is a new product of network reform for safe use , The action time of the relay is divided into fast type and delay type , When used together, the trunk line and branch line shall be protected by classification .
